The pH value of starch can vary depending on the plant source, processing method, and any additives used in the production process. However, in general, the pH of starch is typically neutral or slightly acidic, with a range of around 5.0 to 7.0.
The pH of starch is important in various applications, such as in the food industry, where it can affect the texture, stability, and taste of food products. For example, the pH of starch can affect the gelatinization temperature and viscosity of starch pastes, which can in turn affect the texture and mouthfeel of food products.
In addition to its effect on food texture and quality, the pH of starch can also impact its functionality in industrial applications, such as in papermaking, where the pH of the starch paste can affect the strength and properties of the paper.
It’s important to note that the pH of starch can be influenced by various factors, including the source of the starch, the method of processing, and any additives or treatments used during production. Therefore, it’s important to consider the pH of starch when selecting a specific type of starch for a particular application, and to ensure that the pH is within the appropriate range for optimal performance.
pH value of different types of starch
The pH value of different types of starch can vary depending on the plant source, processing method, and any additives used in the production process. Here are some approximate pH values for common types of starch:
- Corn starch: The pH value of corn starch is typically in the range of 5.4 to 7.0.
- Potato starch: The pH value of potato starch is typically in the range of 5.0 to 7.0.
- Rice starch: The pH value of rice starch is typically in the range of 6.0 to 7.5.
- Tapioca starch: The pH value of tapioca starch is typically in the range of 5.0 to 7.0.
- Wheat starch: The pH value of wheat starch is typically in the range of 5.5 to 7.0.
It’s important to note that these are approximate values and the actual pH of a specific type of starch may vary depending on factors such as the processing conditions and any additives used in the production process.

Are there any standard for the pH value of starch?
There are no specific standards for the pH value of starch as it can vary depending on the plant source, processing method, and any additives used in the production process. However, there may be pH requirements or recommendations for specific applications or industries that use starch. For example, the food industry may have guidelines or regulations on the acceptable pH range for starch used in food products.
